I just had an interesting chat with the fellow who D&D electronics refers
technical support to. His name is Tom Page. He has developed a modification
kit (or instructions - not sure which) for the universal descrambler. He
did give some ideas to help achieve stable lock-up over the phone.
1. Change the trimmer caps to Radio Shack 273-1340A.
2. Change R2 to 5K RS 271-1714.
3. Ground the case of the crystal to C22 ground.
4. Change C21 to 1 ufd.
5. Change c30 to 100pf
6. If necessary add a "hot shot" switch that grounds IC6-10 momentarily..
I suspect that grounding the crystal and the C21 & C30 changes may help..
For more info you can call Tom at 407-799-4292 or can order his mod's
at:
KDA
PO Box 320404
Coco Beach, FL 32932
I really don't know if his mod kit is worth the $10 he wants for it - but
then again if it works...
